One can actually measure just how much any media outlet is “je suis” Charlie. There is an arcane part of game theory that looks at the actions people take to prove how strongly they support a proposition, idea or movement. The wording changes for these actions, they were called “tells” in my day (before poker grabbed the term) so I will use “tells”. In general a strong “tell” is when someone gives something significant of themself (time, money, effort), or puts something of theirs at risk to back a position. A weak tell is when they will put very little of their assets or themselves at any risk.
Take three guesses wether most support is a strong tell. No, actually, take one guess. It’s all you need.
